+### Controlling text fontsize with uniformtext
+
+For the [pie](/r/pie-charts), [bar](/r/bar-charts), [sunburst](/r/sunburst-charts) and [treemap](/r/treemap-charts) traces, it is possible to force all the text labels to have the same size thanks to the `uniformtext` layout parameter. The `minsize` attribute sets the font size, and the `mode` attribute sets what happens for labels which cannot fit with the desired fontsize: either `hide` them or `show` them with overflow.
